    Correct

    • A 32 yr. old male who was on methadone has suddenly collapsed while running and was found dead. What is the most likely cause for his death?

      Your Answer: Prolonged QT

      Explanation:

      Methadone and cocaine can cause QT prolongation through the direct effects on the resting membrane potential. Methadone can increase QT dispersion in addition to QT interval. Methadone inhibits the Human Ether-a-go-go Related Gene (hERG) and causes QTc prolongation and development of Torsades de point. Brugada-like syndrome is another condition found in methadone users which predisposes the users to life-threatening ventricular tachycardia and sudden cardiac death.

    Incorrect

    • Which of the following indicates the opening of tricuspid valve in jugular venous waveform?

      Your Answer: a wave

      Correct Answer: y descent

      Explanation:

      The a wave indicates atrial contraction. The c wave indicates ventricular contraction and the resulting bulging of tricuspid valve into the right atrium during isovolumetric systole. The v wave indicates venous filling. The x descent indicates the atrium relaxation and the movement of the tricuspid valve downward. The y descent indicates the filling of the ventricle after tricuspid opening.

    Correct

    • A 60 yr. old female presented with difficulty in breathing. What is the clinical sign that will indicate the presence of established pulmonary hypertension?

      Your Answer: Raised jugular venous pressure

      Explanation:

      A prominent A wave is observed in the jugular venous pulse and this indicates the presence of established pulmonary hypertension. In addition the pulmonic component of the second heart sound (P2) may be increased and the P2 may demonstrate fixed or paradoxical splitting. The signs of right ventricular failure include a high-pitched systolic murmur of tricuspid regurgitation, hepatomegaly, a pulsatile liver, ascites, and peripheral oedema.

    Incorrect

    • A previously well 33 yr. old female was admitted with a history of recurrent episodes of palpitations. She didn't have chest pain. She frequently drank plenty of coffee and alcohol. Her blood pressure was 120/80 mmHg and pulse rate was 200 bpm which was regular. There was no sign of heart failure. Her ECG revealed narrow complex tachycardia. She was given 3mg of IV adenosine but there was no response. Which of the following is the most appropriate management if she doesn't respond to 6mg of IV adenosine?

      Your Answer: 12mg IV adenosine

      Correct Answer:

      Explanation:

      Vagal manoeuvres can be tried first. If not responding to these then adenosine can be trialled. If 3mg of adenosine has no effect, then give adenosine 6 mg rapid IV push. If patient does not convert, give adenosine 12 mg rapid IV push. Can repeat 12 mg dose of adenosine once if there is no response. If no response, diltiazem or beta-blockers can be given as alternatives.

    Incorrect

    • A 25 yr. old previously well male presented with chest discomfort and difficulty in breathing while running to the bus. Symptoms disappeared after resting. But the symptoms reappeared whilst he was climbing the stairs. On examination he was not dyspnoeic at rest. BP was 110/70 mmHg and pulse rate was 72 bpm. His heart sounds were normal. There was an additional clicking noise in the fourth left intercostal space which is heard with each heart beat. Which of the following is the most probable cause for his presentation?

      Your Answer:

      Correct Answer: Spontaneous pneumothorax

      Explanation:

      The given history is more compatible with spontaneous pneumothorax. Left-sided pneumothoraxes may be associated with a clicking noise, which is heard with each heart-beat and can sometimes be heard by the patient.

    Incorrect

    • A 65 yr. old man with hypertension presented with sudden onset right arm weakness which resolved after 10 hrs. He has had 2 similar episodes during the last 6 weeks. On examination his blood pressure was 140/80 mmHg and pulse rate was 88 bpm. His ECG showed atrial fibrillation and the CT scan of his brain was normal. Which of the following is the most appropriate management for this patient?

      Your Answer:

      Correct Answer: Warfarin

      Explanation:

      CHA₂DS₂-VASc score is used for atrial fibrillation stroke risk calculation.
      Congestive heart failure – 1 point
      Hypertension – 1 point
      Age ≥75 years – 2 points
      Diabetes mellitus – 1 point
      Stroke/Transient Ischemic Attack/Thromboembolic event – 2 points
      Vascular disease (prior MI, PAD, or aortic plaque) – 1 point
      Age 65 to 74 years – 1 point
      Sex category (i.e., female sex) – 1 point
      Score of 2 or more is considered as high risk and anticoagulation is indicated. This patient’s score is 4, so he needs life-long warfarin to prevent a stroke.

    Incorrect

    • A 70 yr. old man underwent temporary transvenous pacing. While in the coronary care unit he developed pre-syncope. His pulse rate was 30 bpm. His ECG showed pacing spikes which were not related to QRS complexes. What is the most appropriate action that can be taken?

      Your Answer:

      Correct Answer: Increase the pacing voltage to a maximum

      Explanation:

      Pacemaker spikes on the ECG indicate that pacemaker is functioning. The most probable cause for this presentation is the change of the position of the tip of the pacing wire. Increasing the voltage will solve the problem. If it works, repositioning of the pacing wire should be done.

His father passed away at the age of 40 due to sudden cardiac death. Echocardiography showed evidence of hypertrophic cardiomyopathy. His 24 hr ECG revealed several short runs of non sustained ventricular tachycardia (VT). Which of the following is the most appropriate management for this patient?

      Your Answer:

      Correct Answer: Implantable cardiovertor defibrillator

      Explanation:

      This patient has a high risk of sudden cardiac death due to a strong family history and non sustained VT. So the most appropriate management is implantable cardiovertor defibrillator.

    Incorrect

    • A 55 yr. old man presented with retrosternal chest pain associated with excessive sweating and vomiting. On examination his BP was 100/60 mmHg and pulse rate was 72 bpm. Bibasal crepitations were auscultated. His ECG showed ST elevation in V1 to V4 and ST depression in leads II, III and aVF. Which of the following would be the finding during angioplasty?

      Your Answer:

      Correct Answer: Complete occlusion of the left anterior descending artery

      Explanation:

      The ECG findings are suggestive of anterior myocardial infarction and the most likely artery affected is the left anterior descending artery. Occlusion of the right coronary artery will be shown by ST elevation in lead II, III, aVF and occlusion of the circumflex artery will show changes in leads I, aVL, V5 and V6. To have ST elevation, there should be complete occlusion of the artery.

    • A 35 yr. old female with systemic lupus erythematosus (SLE) was brought to Casualty, complaining of chest pain and worsening difficulty in breathing for the past 36 hrs. On examination she was tachypnoeic, her BP was 85/65 mmHg and peripheral oxygen saturation was 98% on air. Her cardiac examination was normal but her jugular venous pressure was elevated. She didn't have ankle oedema. Her ECG showed sinus tachycardia and her CXR showed clear lung fields with a slightly enlarged heart. Which of the following is the most appropriate next step?

      Your Answer:

      Correct Answer: Urgent transthoracic echocardiogram

      Explanation:

      Acute breathlessness in SLE can be due to a pericardial effusion or a pulmonary embolism. Normal peripheral oxygen saturation and normal ECG, make the diagnosis of pulmonary embolism less likely. To exclude pericardial effusion, an urgent transthoracic echocardiogram is needed.

    Incorrect

    • A 70 yr. old male patient presented with chronic congestive heart failure. Which of the following is the most important factor to consider when prescribing drugs for this patient?

      Your Answer:

      Correct Answer: Administration of a B-blocker reduces the time spent in hospital

      Explanation:

      It is proven that spironolactone has survival benefits and loop diuretics only give symptomatic relief. Beta blockers are however, known to improve exercise tolerance, left ventricular function and reduce symptoms. They also reduce the mortality associated with heart failure. So administration of beta blockers will reduce the time spent in hospital by improving symptoms.

He didn't have difficulty in breathing and the pain wasn't exacerbated by deep inspiration or a change in position. His father had died due to a heart disease when he was small. He also has a cardiac murmur which was never properly investigated. On examination he was tachycardic with a BP of 165/60 mmHg. There was a diastolic murmur at lower left sternal border which is best heard with the patient sitting forward. Which of the following is the most probable cause for his chest pain?

      Your Answer:

      Correct Answer: Aortic dissection

      Explanation:

      The most probable diagnosis is Marfan’s syndrome because of a family history of cardiac death and heart murmurs. A characteristic feature is pain which radiates to the back. A wide pulse pressure and a diastolic heart murmur is suggestive of aortic dissection.

    • A 50 yr. old male presented with acute severe central chest pain and acute ST elevation myocardial infarction was diagnosed. He was treated with streptokinase. 2 days later he was sweating excessively and he was found to be hypotensive. Which of the following cannot be considered as a reason for this presentation?

      Your Answer:

      Correct Answer: Hypotensive effect of streptokinase

      Explanation:

      Hypotensive effect of streptokinase occurs during the streptokinase infusion which is usually transient. Acute mitral regurgitation due to rupture of papillary muscles, ventricular septal defects and reinfarctions (left or right) are known to cause hypotension after 24 hrs. Pulmonary embolism is less likely but cannot be excluded.

    Incorrect

    • A 60 yr. old man presented with difficulty in breathing. On examination he was severely dyspnoeic and tachycardic. What is the clinical sign that would favour the diagnosis of cardiac tamponade over constrictive pericarditis?

      Your Answer:

      Correct Answer: Pulsus paradoxus

      Explanation:

      Pulsus paradoxus is defined as the exaggerated fall in systolic blood pressure during inspiration by greater than 10 mmHg. Cardiac tamponade is the classic cause of pulsus paradoxus. Kussmaul’s sign (a rise in the jugular venous pressure on inspiration) is mostly seen in constrictive pericarditis. Hypotension, muffled heart sounds and raised JVP can be seen in both conditions.

    Incorrect

    • A 60 yr. old male smoker and a known hypertensive presented with central chest pain radiating to the back. On examination he was tachycardic and hypotensive. His ECG showed inferior ST elevation and his transoesophageal echocardiogram showed a double lumen in the ascending aorta. Which of the following is the most probable diagnosis?

      Your Answer:

      Correct Answer: Dissecting aortic aneurysm

      Explanation:

      The classic history in this high risk patient is suggestive of a dissecting aortic aneurysm. His transoesophageal echocardiogram confirms the diagnosis. ST elevation in ECG is probably due to the extension of the dissection of the aorta which results in compromised coronary blood supply.

    Incorrect

    • A 70 yr. old female was brought in by the paramedics after she collapsed whilst shopping. She has a tachycardia of 150 bpm and her BP is 100/60 mmHg. Her ECG showed a broad complex tachycardia. Which of the following is more suggestive of a ventricular tachycardia (VT) over a supraventricular tachycardia (SVT) with aberrant conduction?

      Your Answer:

      Correct Answer: Atrioventricular dissociation

      Explanation:

      To differentiate VT from SVT with aberrant conduction the following electrocardiographic features should be looked for:

      Evidence of preceding atrial activity for SVT. Oesophageal leads are helpful if P waves are hidden in the QRS complex.
      QRS duration more than 140 ms for VT.
      QRS morphology: Features of QRS morphology that favour SVT are RBBB or triphasic patterns like rSR in V1 and qRS in V6. Monophasic pattern like R or qR in V1 and rS or QS in V6 or multiple morphology QRS complexes favour VT.
      AV dissociation for VT.

    • A 13 yr. old boy presented with difficulty in breathing on exertion. According to his mother who was also present, his exercise tolerance has been gradually worsening for the past weeks. It has reached the point where he is unable to participate in his weekly soccer match. Cardiac catherization was performed and the results are given below: (Anatomical site vs Oxygen saturation (%)vs Pressure (mmHg)) Superior vena cava: 73 ,–. Right atrium: 71, 6. Right ventricle: 72, –. Pulmonary artery: 86, 53/13. PCWP: –, 15. Left ventricle: 97, 111/10. Aorta: 96, 128/61. Which of the following is the diagnosis?

      Your Answer:

      Correct Answer: Patent ductus arteriosus

      Explanation:

      The oxygen saturation in the pulmonary artery is higher than that of the right ventricle. The pressure of the pulmonary artery and of the PCWP are also high. So patent ductus arteriosus is highly suggestive.

      Your Answer:

      Correct Answer: Chewable aspirin 300 mg

      Explanation:

      The diagnosis is inferior ST elevation myocardial infarction. As the right coronary artery supplies the SA and AV nodes and bundle of His, conduction abnormalities are more common with inferior MIs. The most immediate drug management is high dose Aspirin. Definite treatment is urgent cardiac revascularization.
